The present invention realizes the miniaturization of an ink jet recording apparatus by improving the tube arrangement (pull-around) structure. A flow passage of ink supplied from an ink cartridge is turned by approximately 90° using an elbow member, and ink tubes which are connected to the elbow member are arranged (pulled around) to extend toward an image recording part through gaps defined between a plurality of atmospheric-pressure introducing sleeves along an outer wall of the cartridge casing. Due to such an arrangement, compared to a case in which the ink flow passage is turned by approximately 90° using the flexibility of the ink tubes, it is possible to turn the ink tubes with a remarkably large radius of curvature and, at the same time, it is possible to decrease a size of a gap defined between the outer wall of the cartridge casing and other equipment such as a waste ink box. Accordingly, the present invention can realize the further miniaturization of a multi-functional device.
